I have been trying to figure out why my QNAP TR-004 is comparatively slow when connected directly to my Mac Studio via USB, as compared to when I access it over a local 10GBe network and it is attached to my QNAP TVS872XT. I have 4 20TB Ironwolf drives configured in Raid 0, and when I connect to the TR-004 via the TVS872XT, I get read speeds up to about 1000 MB/s, but when I connect it directly to my Mac Studio, that drops to 200 MB/s (and sometimes it caps out at 40 MB/s). I have filed a ticket with QNAP support, but they are not very helpful in figuring this out. I thought you might have some perspective on what might be going on here to help me diagnose or fix the problem. The issue is that I sometimes need to use the TR-004 as a DAS (when traveling), and sometimes I need it connected to a NAS for access. If you have any thoughts, I would appreciate it!

I added a 32GB RAM module to my Synology RS820+ and when I go to the resource monitor screen, it shows the 32GB. But the Info Center page shows only 2GB, and what's worse is the Virtual Machine Manager can only access 2GB. The whole reason I added the RAM was for running VMs. Is there any way to fix this? The RAM seller indicated that their RAM was compatible with my NAS model. But perhaps they didn't thoroughly test it.

Hi, Ive been pouring over your reviews of 2 particular Nas machines and cant decide between them
1. Qnap TS435 short rackmount
2. Terramaster u8-450

I realise the terramaster has 8 bays, which is more than I need, but good for the future while the Qnap has some inbedded graphics. I don't have any use for plex, or similar, as I don't have any media on hard drives (for now) and mainly need a file server to run NextCloud and VMs, maybe some VOIP phones.
I have 10gb networking so both are attractive in their 2 SFP+ ports.

I cant decide between the cheaper QNAP with "better" software and embedded graphics or the slightly more expensive non graphics Terramaster which offers more future proofing and the ability to have TrueNas. My only worry is the very low end CPU - Atom C3558. It seems less powerful than a £50 raspberry pi - should I be worried about it.

I would love your thoughts, thanks in advance.

So, this is the 2nd time in 2 years that I have lost some important data on my Asustor AS6510T

I have 5x 18Tb drives in Raid 5 , Btrfs and 2x 1Tb SSD for caching

First time was in 2022 with during the Deadbolt attack, but the data loss was not due to Deadbolt (although a few less important files), but due to the ADM update to fix it :
- after the attack, the NAS hung for 30mins in the initialization phase, so I couldn't install the ADM update
- removing the SSDs made it start up with the new ADM but did not recognize my Volume 1 (corrupted)
- after trial and error, I put the SSDs back in and it suddenly recognized my Volume 1 again although some files were lost

Last week, I bought 2x extra 18Tb to increase my volume size and upgrade to Raid 6
- I did "safely remove cache" in ADM, but after 30mins, it was still suck on 0%
- So I had no other resort than trying a hard reboot (in hindsight I should have waited for hours, but who would expect a 1Tb SSD flush would take hours..) and that's when my Volume 1 was inaccessible
- I took the SSDs out, rebooted and back in and then it recognized my Volume 1
- I then safely remove my SSDs (this time it took 15mins)
- ADM started immediately a rebuild
- after the rebuild, I got a weird status (see attached pics) :

• RAID Level RAID 5 : Drive 1, 2, 3, 4, 5, 5 (2 times 5!!)
  
• RAID 5, data protection None (Faulty drives tolerated 0), even though I have 5x disks of 16.37 Tb (18Tb) and a total volume capacity of 65.47 Tb.

Evening all

As a relative newbie to having a NAS (21Tb RAID 5), I am now rapidly running out of space so would like to add an expansion cabinet which I would then populate with 4 additional Seagate 12Tb Ironwolf NAS drives.

I am currently running RAID 5 on my Asustoir, so how would I add these drives thus increasing my capacity or do I have to create a seperate RAID array ?

Advice and or guidance would be much appreciated.

It is used for 3 PC b/u (Acronis Cyber protect) and also as a PLEX server(a;llso backup).

Many thanks from a new member.

Hello everyone

New member here with a question about re-use of HDD


Situation is I have upgraded to a 4bay 918+ from a 2 bay 214 Play

For a number of reasons the migration route ended up being an old school copy -the 214 has not been used for anything fancy so I just needed to move the data across and I duplicated the folder structure albeit under a new admin/user account etc

So I now have a 918+ with 2 new 4Tb drives in SHR and the same data as the 214 Play which still has the old 4Tb drives also in SHR

The drives in the 214 are only about a year old and SMART testing OK so I want to add them to the 918+ as a 3rd and 4th drive 

My question is how can I re-use them.  Can I just remove them one by one from the 214 and insert them into the 918+ without doing anything first?

Would the 918 will see each as a new drive and will reformat them and then add them to the SHR so it effectively goes from a mirrored RAID 1 to RAID5?

As they are currently in an SHR array, albeit a mirror, is that going to be a problem in the new NAS?

I have searched for an answer without success and Google etc only really deals with data migration, not re-use of hard disks that were in an array

Thanks in advance

Hi there,

I'm in the creative field and need a NAS that can handle a bunch of different tasks. I need to store and back up my photos, videos, and various work documents. I also want to back up my Mac and iOS devices. On top of that, I'm looking to host a website through the NAS since I do web design, and I'd love to set up a library for streaming videos and music at home.

Could you recommend some NAS models that would fit these needs, especially ones that are easy to use, scalable, and offer good streaming quality?

Thanks for your help!

Now that QNAP has removed Plex from its HD Station, what is the point of HDMI output now? Even QNAP said that including "HDMI out" on it's Plex page was misleading.

Current system is getting slow and I would like to store my cd collection and expand use case I want future growth a looking to upgrade my home network and switch to at least 2.5 gb I have been looking at the QNAP tv473A along with the TVS-h474. Not sure if its worth the money

Hi Thank you for providing this services. This is my first time being in contact with you.
I have an arhcitecture firm i started 5 years ago.
I started off with DS223J 2 Bay. This had a fault so i upgrade about a year ago to DS224+
i have this nas synced with a second nas at my house for backup.
in both nas i have 2 8tb hard drives.
the one in the office (DS224+) is almost full.
should i upgrade to a larger nas or buy an extension pack?
i have seen a few extension packs.
i noticed one is a 5 bay. how does this work with raid set up.
thank you
